All eyes were on the High School Musical actress's chocolate brown boots with multiple straps that accentuated her toned, tanned thighs.A set of oversize aviator sunglasses, a grungy tee and piles of necklaces and rings added oomph and attitude to what was actually a rather raunchy look for the star.

The daring outfit is something of a departure from Miss Hudgens' usual style of pretty dresses or pared-down jeans and a fail-safe cardi.Observers may wonder whether the star's sexy style is the result of new beau, actor Austin Butler.

And judging by the pair's passionate display of affection in Bob's Big Boy diner in Burbank this week, they could well be right.
